External Validation of SHAPE Score: A Score to Predict Low-Risk Lower Gastrointestinal Bleeding in the Emergency Department.

Lower gastrointestinal bleeding (LGIB) frequently leads to emergency department (ED) visits and hospitalizations, encompassing a spectrum of outcomes from spontaneous resolution to intrahospital mortality. The purpose of this study was to validate a scoring system designed to identify cases of low-risk LGIB, allowing for safe discharge from the ED. A retrospective analysis of all gastrointestinal bleeding cases presented at three EDs in 2020 was conducted, focusing specifically on patients with LGIB.

Respiratory hospitalizations and ICU admissions among children with and without medical complexity at the end of the COVID-19 pandemic.

Decreased severe respiratory illness was observed during the first 2 years of the COVID-19 pandemic, with a relatively smaller decrease among children with medical complexity (CMC) compared to non-CMC. We extended this analysis to the third pandemic year (April 1, 2022, to March 31, 2023) when pandemic public health measures were loosened. A population-based repeated cross-sectional study evaluated respiratory hospitalizations among CMC and non-CMC (<18 years) in Ontario, Canada.

Discovery of Potent Azetidine-Benzoxazole MerTK Inhibitors with Target Engagement.

Inhibition of the receptor tyrosine kinase MerTK by small molecules has the potential to augment the immune response to tumors. Potent, selective inhibitors with high levels of target engagement are needed to fully evaluate the potential use of MerTK inhibitors as cancer therapeutics. We report the discovery and optimization of a series of pyrazinamide-based type 1.
